Just want to get the opinion of those with Common-Rail Diesel engine-powered rides - be it Troopers, Innovas, or Benzes - to share their impressions in terms of performance, noise/vibration level, and fuel economy. Especially fuel economy!

CRD fuel economy is supposed to range around 44 mpg (18km/li) for a 2.5 li to a 3.0 li displacement engine (well that's what most brochures claim) combined for both city and hiway driving. Just want to know first-hand from owners if there's any truth to this.

Thanks!
